OK, just came back from another Target store trying to do the price adjustment again. This time it didn't go as smooth as the first one I did at another Target store. So here is what happened - I tried to do the price adjustment for the two Ambush ships that I paid for $70 each. The girl at register was extremely helpful and she tried to help me return the items and re-purchase it without hassles, but then the evil supervisor walked by and told the girl she can't do that. The supervisor said the store policy is all return clearance items must go back to the shelves first before they can be re-purchased. So the supervisor put the Ambush boxes on the cart and asked me to wait for the handler to put them back to the shelves first. I waited for about 40 minutes... and the handler never showed up.
Luckily the store closes at 11pm, so the supervisor had no choice but had to let me re-purchase it without waiting for the handler to show up. So I walked out the store with 2 Ambush ships at $30 each, plus the last remaining Ambush ship found on the shelves also at $30. So $90 + 40 mins wait time for 3 Ambush ships, I guess not too bad :-)
So it looks like it's quite YMMV.
